The project included the replacement of the H&V system with a new HVAC system, new plumbing piping and fixtures and a fire protection system. Project construction phasing was carefully designed to allow the continued use of the existing steam heating system while new hot water systems came on-line. Eventual conversion to condensing-style high efficiency hot water boiler system with a remote-barrel chiller system serving 4-pipe distribution with vertical unit ventilators and roof-mounted energy recovery units.
